How to save a binary file?
final String link =
    "https://repo1.maven.org/maven2" +
    "/org/jodd/jodd-http/3.9.1/jodd-http-3.9.1.jar";
​
HttpResponse response = HttpRequest
    .get(link)
    .send();
​
byte[] bytes = response.bodyBytes();
​
FileUtil.writeBytes(
    new File(SystemUtil.userHome(), "jodd-http.jar"), bytes);
How to follow multi redirects?
Either use HttpBrowser:
HttpBrowser browser = new HttpBrowser();
​
browser.sendRequest(HttpRequest.get("google.com"));
​
// read response
Response response = browser.getResponse();
String page = browser.getPage();
or the flag followRedirects() to enable the following redirects:
HttpResponse response =
    HttpRequest
        .get("google.com")
        .followRedirects(true)
        .send();
What is the difference between HttpRequest and HttpBrowser?
HttpRequest represents just a single request; clean and simple.
HttpBrowser emulates browsing of a website (i.e. set of URLs) like a browser. Besides sending requests, it also stores and resends cookies, maintaining the current user session. Moreover, the HttpBrowser uses new request on redirection following, allows common request headers for all the requests etc.
Server choses TLSv1.2, but that protocol version is not enabled?
Just add the following property -Dhttps.protocols=TLSv1.1,TLSv1.2 which configures the JVM to specify which TLS protocol version should be used during HTTPS connections.
Since 8u292, JDK 11.0.11, JDK16+ Java requires use of TLS v1.2 or v1.3.
